Hi Ben, It does sound like something to do with describeType(), though I can't see Cairngorm 2.2 could have changed what it returns. Can you compare the describeType() output in the two versions. Have you debugged the application and stepped through the getWebService() call to see whats happening there?

Hi Alistair, _webServices is empty, but we already knew that. Looking at ServiceLocator in the debugger shows all of my WebService objects properly constructed and present, they're just not registered for whatever reason. As far as I can tell, getWebService() does not get called before the first time I try to access one of my WS objects, which is when it bombs. I thought maybe it was because I had forgotten to remove my manual calls to loadWSDL(), but removing those didn't help either. I've been up to date on the Flex SDK for a while now. Like I said, this began as soon as I switched to 2.2 without changing anything else. The _webServices dictionary is populated by calling describeType() and then harvesting the accessors XMLList, correct? I am almost positive that is the problem. WS properties defined in AS don't seem to be included in accessors, resulting in them never getting registered. Let me know what you think. Ben PS - I've converted to an MXML ServiceLocator, so this issue isn't holding me up, I'm just trying to make Cairngorm as robust as possible. --- In [email protected], "Alistair McLeod" <[EMAIL PROTECTED]> wrote: > > Hi Ben, > > I can't think of anything that's changed between 2.1 and 2.2 that > would cause this.
